DO-254 / ED-80 - Design Assurance Guidance for Airborne Electronic Hardware 5.1.2: 5.1.2 Requirements capture activities

Capture should document the system requirements allocated to the item (functionality, performance, segregation, built-in test, testability, interfaces, environment, test and maintenance, power, physical characteristics); identify PSSA safety requirements (assurance levels, probability requirements for malfunction or loss, architectural and functional safety attributes); identify design constraints arising from technology, standards, procedures, the design environment, guidance and production processes; determine derived requirements needed for implementation, uniquely identifying those from the safety assessment with safety implications (for example protection of higher-level functions from lower-level anomalies at their interface, input data ranges and bit states, power-up and reset states, supply demands, time-related functions, all possible state transitions, signal timing in normal and worst case, noise and cross-talk, glitches in asynchronous logic, control of unused functions); feed derived requirements back to the SSA; state requirements quantitatively with tolerances and free of design or verification solutions; return omissions and errors to the system process; and make requirements traceable to the next higher level, with derived requirements flagged and traced down the hierarchy as far as they go.

What else in your programme already covers this

This control maps to 6 controls across 3 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

  • CBA-1 CBA-1 Circuit board assembly development process
  • CD-8 CD-8 Robustness: abnormal and boundary conditions as requirements
  • IP-6 IP-6 Requirements for COTS IP functions
  • 5.3.1.1 5.3.1.1 Safety requirements
  • 5.3.1.8 5.3.1.8 Interface requirements
  • A-2.2 Derived high-level requirements identified and passed to the system and safety processes

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
